Manipulation of vapour split in Kaibel distillation arrangements
چکیده انگلیسی


• Studying the necessity of manipulating vapour split in Kaibel arrangements.
• Identifying the benefit of using active VS control versus the possible loss of a fixed split ratio.
• Approach 1: Vmin diagram to study the effect of VS on energy needs for different feed compositions.
• Approach 2: rigorous simulations using UNISIM.
• On-line adjustment of the vapour split helps handling expected feed property variations.

In this paper, we want to show how we can gain more from a Kaibel distillation column by considering a degree of freedom which is normally not used. Two methods are used to study the effect of vapour split manipulation, namely a shortcut method and rigorous simulations. Using a case-study, we show that we may not be able to operate close to minimum energy requirement for some feed disturbances as we have the vapour split fixed.
